While initially working directly for the Boma 20,000 years ago during their war with humanity and the fairies, Ruffian Boma ultimately had a change of heart after an encounter with Saint Beast Lakia, who defeated him but respected his courage and healed him as a noble warrior, making the Boma Beast respect the Saint Beast and come to an understanding of who the real enemy was. Taking up Lakia's cause, Ruffian Boma attempted to attack his former leader Lagorn, but was easily defeated before being sealed with a Boma Nail and placed in a red pool within Boma Castle.
